SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 622,435, dated April 4, 1899.

Application filed June 24, 1898. Serial No. 684,386. (No model.)

170 all whom it may concern:

Be it known that I, ALONZO D. ANTHONY, of Groton, in the county of Tompkins, in the State of New York, have invented new and useful Improvements in Spring-Hinges, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. r

This invention relates to spring-hinges, having more particular reference to what are known as holdback hinges and are especially adapted for screen-doors, although they may be used, if desired, upon any door.

My object, primarily, is to prod uce a springhinge in which the two butts or leaves forming the same are held together by the pin, so that the two parts are readily detachable, such spring-hinges being adapted for screendoors or for other doors which it is desirable to remove during certain seasons of the year; and to that end my invention consists inthe several new and novel features of construction and operation hereinafter described and which are specifically set forth in the claims hereunto annexed.

It is constructed as follows, reference being had to the accompanying drawings,in which- Figure 1 is an outside view of the hinge complete, a portion of the shell inclosing the shell being broken away. Fig. 2 is a reverse view thereof, showing the interior of the shell.

Fig. 3 is a similar View thereof, showing the pin partially removed. Fig. 4 is a vertical section on line 00 :0, Fig. 2. Fig. 5 is a crosssection .on line y y, Fig. 2. Fig. 6 isa crosssectionon line .2 5, Fig. 2; Fig. 7 is an isometrical elevation of the disk, its post, and extending end.

ct is a leaf or one of the butts forming part of the hinge, having ears a, the upper one of which is provided with a vertical pin-opening a and the other with a pin-recess a and also having screw-openings for securing the leaf to the jamb. The inner face of the up per car is provided with a slotway b, preferably enlarged somewhat at its outer end, so as to easily engage the post with which it comes in contact, which will hereinafter be more fully set forth.

I) is the opposite leaf or butt, having constructed integral therewith a shell or casing 11, adapted to rest between the ears a, as

shown in the drawings, said shell being provided at its lower end with a pin-opening c and at its upper end with an enlarged opening 0 for the purposes which will presently appear. The interior of the case is also provided, just at one side of the center, with a post 0, upon which the actuating-spring d is mounted, the lower end of said spring resting within a socket d',formed within the shell, Where it is held rigidly and moves with the shell.

e is a disk perforated centrally, as shown at e, to allow the pin 6'' to pass through it and is provided upon one side (the upper side) with a post 6", which engages with the opening 0, the said post terminating in an elongated end f, as shown in Fig. 5. The said elongated end f is adapted to extend above the upper end of the shell b". The disk 6 is also provided upon one side with a lug f, adapted to engage with a lug 9, located upon the inner face of the shell, as shown in Fig. 6, so that when the spring is in operation the disk will be limited in its rotation. The opposite edge of the disk, or nearly opposite edge of the disk, is provided with a recess g, which receives the upper end of the spring 01 and causes said end of the spring to rotate with said disk.

The leaves of the spring may be constructed of cast-iron or in any other well-known manner.

It will be observed that when the parts are put together as above indicated the swing of the springs will cause the disk 6 to rotate within the shell and carry with it the upper end of the spring, while the lower end of .the spring is held stationary, thereby producing a tension upon the hinge, the said diskbeing heldrigid with the upper ear a, owing to the fact that the elongated end f of said disk en- I gages with the slotway b.

. Having described my invention, what I claim, and desire to secure by LettersPatent,

1. A detachable spring-hinge, comprising two leaves, one of which has extending ears, perforated,one of which cars is provided upon its inner face with a slotway, the other leaf having a shell, a disk secured rotatably in the upper end of said shell, a post located in said shell, a spring mounted on said post, one

end of which spring is held rigid with said shell, and the other end engaging the disk, said disk having an elongated end to engage the slotway in the ear of the opposite leaf, and a pin, for the purposes set forth.

2. A detachable spring-hinge, comprising two leaves, one of which has extending ears, perforated,0ne of which ears is provided upon its inner face with a slotway, the other leaf having a shell, a disk secured rotatably in the upper end of said shell, and provided with means to limit its rotation within the shell, a post in said shell, a spring mounted on said ALONZO D. ANTHONY.
